I've vac pressure tested other chainsaws but not a Poulan Strato like this one.
Appears maybe i need to completely remove the block from the case mainly to block off the 4 screw intake manifold port area.
I put 3 different donor carbs on this saw and each one has exact same symptoms, a high idle, the idle screw is completely off the adjuster, throttle butterfly is closed and only way to slow down the low idle is too set the idle adjust jet about 1/2 turn from it's normal setting and then the H will bog. Saw starts good and only runs good at the high idle area and cannot slow down enough to stop the chain clutch. (clutch is good)
Appears to be a air leak and maybe at the carb rubber manifold boot area or ????
Block will have to be removed from the case to get to the FOUR intake rubber intake manifold assembly screws.
I suspect the clutch side seal area because the plastic is melted in this are due to the saw being operated with the chain brake en-gauged.
Anyone have any pointers or comments about pressure testing one of these type Poulan strato blocks.
